You can see a partial legacy of the "Wall of Sound" at most concerts today - vertical line array speakers.

https://www.soundonsound.com/techniques/line-arrays-explaine...

For the most part, each performer plugged into the "Wall of Sound" had their own vertical 1xN stack of drivers.

3 drivers in a vertical line away will have less distortion than 3 drivers in a horizontal array; the horizontal drivers will suffer from comb filtering for listeners who are not located dead center at the middle of the array. (This of course assumes your audience is dispersed horizontally as opposed to floating randomly in space)

Modern home loudspeakers hew to this philosophy as well to an extent. As opposed to big "monkey coffin" 70s speakers with a random array of drivers sprayed across the front of the speaker[1], modern tower speakers have a vertical array of 2 or more drivers whose centers are aligned in a vertical line[2].

> A 30 second tiktok clip can give you the same type of knowledge that a 300 page book can, but it cuts to the chase, and doesn't bury the lead.

Perhaps, but if that is true I highly doubt that you can actually absorb the information in 30 seconds. Doubly so if you quickly move on to the next thing, as tiktok pushes you to do (I guess? haven't used myself).
I dropped out of school (English literature) because I needed to make money and pay bills due to a life change, and i applied at a place that does internet stuff to do tech support because computers were a big part of my hobbies. I moved up over the years learning as I went and now I've occupied a few 'engineering' roles. I used to feel somewhat embarrassed to hold an engineering role with no engineering degree.

But I stopped worrying the more I worked with software engineers. They were just people, some sucked, some were great, their education almost never had anything to do with the bracket they fell into. The worst one I've ever met has a PhD. The best one I've met also has a PhD.

Then I found more people in these positions that have degrees or no degrees, and the people that work well both with degrees and without had something in common. They can more or less be taught to do anything, they can extrapolate and apply knowledge outside of the specific example initially given, and they understand the big picture/desired end results. I hate to say it so crass, but they are good at identifying the trivial bullshit and addressing it or cutting through it rather than sitting in it. They "Get it." From the ideal to what the business demands, they just get it.

Training competent people is a boon. I don't know how you seek out interested/curious competency and then train it, but if we can figure that out, it'd be cool. I'm really tired of working with people who have degrees and jobs because their mothers told them it pays well. Computer Scientists with no interest or curiosity about computers.
> Sean Carroll's blog entry

While this is a good blog post on this topic, I would point out that Carroll does gloss over one crucial point. He says:

"[T]he best you can rigorously do is define the energy of the whole universe all at once, rather than talking about the energy of each separate piece."

What he is glossing over here is that you can't "rigorously" do this unless your standard of "rigor" is looser than it is supposed to be in GR. Any way of defining "the energy of the whole universe" will involve what are called "pseudo-tensors", which depend on particular choices of coordinates. The standard of rigor in GR is supposed to be that everything that has physical meaning is expressed in terms of tensors, i.e., objects that do not depend on particular choices of coordinates. By that standard, it is not possible to "rigorously" define "the energy of the whole universe", as I pointed out in another post upthread.
In the NYC public libraries there are kids sections where you just walk around and look at books. If something seems interesting then pick it up and read it. I preferred things with technical pictures so the kids section was quite boring.
> The way Apple handles storage and memory means ENTIRE devices need to be replaced when a new larger SSD or a few more gigs of memory are all that's really needed to keep a device in service for a few years longer.

Most iPads are vastly overpowered and last for a long time. If someone needs more power/storage, then one usually passes them to the next person which might use it for many more years.

My old iPad Air 2 from 2024 is still used.

> Even the iPad could probably use an M.2 SSD!

Most users don't need that. I'm using fixed storage in my Macs (and iPads) for years. I've attached additional storage to USB-C for many years without problems.
I am aware that there are differences, I just took RAM DIMMs as a reference because there is a >0% chance that anyone reading this has actually ever bought a comparable product themselves.

As for prices, the prices you cited are not at all comparable. Apple is absolutely certainly buying directly from manufacturers without a middleman since we're talking about millions of units delivered each quarter. Based on those quantities, unit prices are guaranteed to be substantially lower than what DigiKey offers.

Based on what little public information I was able to find, spot market prices for LPDDR4 RAM seem to be somewhere in the 3 to 5$ range for 16GB modules. Let's be generous and put LPDDR5 at tripe the price with 15$ a 16GB module. Given the upgrade price for going from 8 to 16GB is 230 EUR Apple is surely making a huge profit on those upgrades alone by selling an essentially unusable base configuration for a supposed "Pro" product.
In fact they probably care that it's not easily portable

The fact that these musicians are not played despite producing 'good music' refutes the author's thesis. Crappy pop music is played way more often. Even bad music from decades ago gets more airplay. Music disappears when there is simply no audience for it. It has nothing to do with goodness.
Look, my coffee routine is _perfectly reasonable_.

Fractional gram dosing, multiple pours at different temperatures, timed switch from immersion to percolation, and benchmarking different filter papers has a _measurable impact_ on my coffee.

And I have the data and refractometry measurement data to show it.

... Admittedly the refractometer was expensive, and incorporating it into the routine is complex and not very intuitive.

I can also assure you that I don't look cool while doing it.
Cross platform toolkits, more than other software components incur massive tradeoffs. They’ve written one themselves, tailored to their needs and open sourced it along the way. I guess I don’t see the problem here. If one that’s existed for decades fits your needs better then use that.
Yes, that is correct. The incentive is that our net terms go from 90 days to same day payment.
Feynman has a fantastic anecdote about getting over what we might today call burnout. He was not interested in work at all in his professorship, when he noticed a wobble in a plate being thrown, and wondered about it. He spent all day working on the physics of this toy problem, and claims discovering play as the key to his recovery.

If you haven't read them yet, "Surely You're Joking, Mr. Feynman", and "What Do You Care What Other People Think" were great reads in my 20s.
> common signal in both (i.e. the sound coming out of the speakers) is nulled out, but the difference signal (the voice) makes it through.

What drives this? Singers and speakers are both localized sources, so I'd expect the mics to pick up similar phases for each.

I bet it's distance! Falloff depends on distance to source, so there should be a larger difference in volume for closer sources.
> The "design of WebGPU" is a problem. It's designed for the web to be secure and sandboxed so the API design reflects that.

The page you linked clearly states that wgpu-hal's API is extremely unsafe and skips many checks in order to reduce overhead. So while "secure and sandboxed" explains why wgpu wasn't chosen, it doesn't explain why wgpu-hal wasn't chosen.

You might like Cormac McCarthy's "All the Pretty Horses" [0]. The prose style is idiosyncratic, but also arguably his most accessible. It's about a 16 year old crossing over into Mexico and with little else but the clothes on his back and love for horses, but not "juvenile" --- if anything the author elevates the teen's stumbles into love, adventure, and heartbreak, into a grand vision of the American frontier.

Weird. At 9 I randomly picked whatever looked interesting. If I liked it, I proceeded to read every single other thing by that author.

There was no "word of mouth" because I was the only kid in my class who read for pleasure.
I wonder if this will bring a new widely available high-performance connector to the wider market. SO-DIMM connectors have been occasionally repurposed to other uses, most notably by Raspberry Pi Compute Models 1-3 among other similar SOM/COM boards. RPi CM4 switched to 2x 100pin mezzanine connectors; maybe some future module could use CAMM connectors, I'd imagine they are capable enough

Well there are protocols, procedures and a bunch of checks and balances.

The problem with the LLM is that there isn't any, its you vs one shot retrieval.
> I think if big game studios, rather than dumping their copious amounts of money into single, giant-scope games, dealt it out amongst a variety of smaller teams for smaller-scoped projects, they'd be way better off.

Yeah one microphone was behind the other, though I was under the impression it was half a wavelength behind and thus created something quite akin to modern active noise-cancellation?

From how they've been talking about Zed (on The Changelog, among other places), I expected to be wowed on my first open of the application, but the experience kind of fell flat for me. I might try it again when they have some better onboarding, though!
Coding tests are an awful place to test someone’s conversational skills. I don’t talk while I code. You don’t either. Honestly I can’t even remember the last time I talked to anyone about the code itself outside of a PR. People talk about architecture and database migrations and why their containers aren’t behaving locally. Nobody ever tests for that stuff.
I feel like this is the perfect application of running the data multiple times.

Imagine having ~10-100 different LLMs, maybe some are medical, maybe some are general, some are from a different language. Have them all run it, rank the answers.

Now I believe this can further be amplified by having another prompt ask to confirm the previous answer. This could get a bit insane computationally with 100 original answers, but I believe the original paper I read was that by doing this prompt processing ~4 times, they got to some 95% accuracy.

So 100 LLMs give an answer, each time we process it 4 times, can we beat a 64 year old doctor?
Apple uses Magic Compression.

There is an "American" on-site battery backup startup (for residences & biz) which AFAIK plans to use Chinese hardware and Russian software.

Yeah, the assumption seems to be that using less battery by one component means that the power will just magically go unused. As with everything else in life, as soon as something stops using a resource something else fills the vacuum to take advantage of the resource.

Flavor compound release is affected by method, temperature, and wat. The method (which includes temperature, but is not restricted to it) extracts certain compounds. The release is affected by temperature and the amount and type of compounds in solution. It's entirely possible that warming up a cold-brewed coffee could create off-flavors.

If you let coffee and water sit for long enough, all the compounds that can be extracted, will be extracted. But those compounds will also start to break down over time. Heating and oxidation accelerates the breakdown.

When you go to taste coffee, the compounds in the coffee either expand or contract depending on the temperature, and solubility. So the temperature you drink it at, along with water concentration, determines the flavors. (Flavor is actually aroma, taste only has 5 basic senses)
I'm not talking about LLMs in particular. I guess this is a company wide mandate to grow knowledge of how to do this stuff well, I mean that makes sense. But in the trenches (aka hells-ahole) that means a lot of bad bad stuff is being relied on and it generates calcification of business segments and kafkaesque anti-patterns for the uninitiated. This doesn't only apply to "AI" its a generic feature of shoe-hornings. The problem with the shoe-horn is that its politically costly to resist even if it makes good business sense to resist at the micro level.

The situation with kids is an issue. However, about the mean attacks online mentioned in the article, the American Library Association president, unfortunately made a rather poorly chosen quote at almost the inflection point they're describing, in April 2022. Arizona, Idaho, Illinois, Georgia, Louisiana, South Carolina and Wyoming pushed to withdraw from the ALA after the quote. Per [1], on being elected, Drabinski wrote:

> “I just cannot believe that a Marxist lesbian who believes that collective power is possible to build and can be wielded for a better world is the president-elect of @ALALibrary”

Sure, it's a single tweet. It mentions a better world. However, I also suspect most normal Americans with slight sense of political winds right now (Ukraine, Feb, 2024?? 2 months?) might comprehend why labeling yourself as a "Marxist lesbian" who "wields collective power" might be taken wrong by some of America on being elected to lead all American libraries.

I used to work for/with the Feds, and I think they would have been justifiably mad if I had very publicly announced I was a Marxist who wields power in the Feds on election.

Lying for what? They did not promise not to close studios or laying off people. Governments should start looking at their own layoffs first too.
MAD makes sense if you assume the participants are rational and have accurate information. That's probably true on average in the long-run. But what bothers me is that it only takes one accident or miscalculation or crazy president to bring about the end of the world. And we've certainly had our fair share of close calls with bad sensor readings or training tapes being put into a live operational setting.
Oh those megahertz myths! Their marketing department is pretty amazing at their spin control. This one was right up there with "it's not a bug; it's a feature" type of spin.

For the presumed improvement to battery life? Because Fw already uses SO-DIMMs.
I meant that you could use the AES branch when running on HW-accelerated AES systems and chacha8 otherwise. Given that the security properties of AES are better understood than chacha8, any issues with chacha8 would have more limited scope. And since this is a cryptographic RNG, the specific implementation doesn't actually matter. The math variant probably would probably need to use the chacha8 variant since that can have reproducability requirements for a given seed although it's arguable if that reproducability needs to be the same between totally different machines since the implementation of math/rng isn't actually defined to have that property & you're already changing this in 1.22 which indicates it's mutable.

I'm kind of surprised that it's slower on AMD Ryzen - it looks like only the Pro series have a an actual co-processor. Weird decision on AMD's part to implement AES-NI without HW acceleration on some CPUs instead of just not implementing the AES-NI instruction set. That being said, AES-CBC would be even better for this purpose since the authentication guarantees aren't needed.

On my Intel machine, it's 5.7 GiB/s for AES-GCM. I don't know how you benchmarked the chacha8 version so I can't run the equivalent on my machine.
I personally think an industry-wide license would be an easier filter than requiring a degree: Schools don't often teach what you need to know, and sitting for an exam is a lot easier for the "I've been in the industry XX years without a degree."

It would also be easier for the industry to settle on some filters in the exam to block people who just SPAM job postings. For example, open jobs for doctors are only posted on websites that are available to doctors. There is no way for the general public to SPAM job listings for doctors.
ISO C versus Reality
> The government is corrupt and inefficient, spending vast sums on homelessness while achieving effectively nothing. Progressives can't blame anyone but themselves since California is a one party state with no real opposition.

Seattle voted the two progressives on city council out (and Sawant retired) some time ago, homelessness has gone nowhere but worse since then. Like clockwork, we're adding another ~1000 street homeless/year.

As it turns out, the opposite-of-progressives don't have a solution for it either. Which isn't surprising, since they've held most of the council seats and the mayor's office for decades, it's just that now they don't have a progressive boogieman to blame for their failures. Meanwhile, Broadway and Pike and Denny and Pine look worse than they ever have, and so do the streets surrounding them.

It's almost like homelessness is an emergent property of a housing shortage.
> I don't think it's strictly for price gouging/segmentation purposes.

I think it is strictly for that purpose.

Another thing to think about that is also sad and just sorta becomes part of the background noise of existing in society is exploitation. If you ignore the emotionally charged connotations around the term and focus on its meaning

> make full use of and derive benefit from (a resource).

Capital is in the business of exploiting Labor. It is the only thing that makes sense in our economic system. For anyone doing labor for $X for a company that then sells it to a customer for $Y it must hold that X < Y or else the company will fail. The arrangement most people operate under, myself included, is one where you are willingly underselling yourself. The trade off that most people point to is that the people are willing to do this because the stability of getting $X all the time regardless of this weeks / months / years sales is worth foregoing $Y, essentially you are buying stability with the difference. Although the recent rash of layoffs for companies, regardless of how well they are doing, does offer a counterpoint to that theory.
Quoting George is a bad look and instantly discredits you as a parrot.

Again, before you can challenge me, I have already challenged you to back up your claim that "it is trash." Quoting George certainly is not that.

I'm not sure this is true.

In the long run, it makes sense to consume power when renewables can supply it, instead of having to store it in a battery and use it later.

In the short term however, renewables can't scale up in demand, so you're actually likely to require that the load is served from dispatchable power, which is probably either gas, hydro, or battery.

I don't think there's really any good time to charge it then. If solar was ever underutilized, I would assume there would be no gas in the mix at that point in time, but there is no such time.
